201-8011 - Miller Smith 200 Series Silverline High Purity Analytical Line Regulator 0-60 PSI

Technical Overview of the Miller Smith 201-80-11 Silverline Regulator

The Miller Smith 201-80-11 is a premium component within the 200 Silverline Series, engineered specifically for high-purity analytical applications. This single-stage line regulator is designed to manage low inlet pressures and provide precise delivery control in environments where diffusion resistance is critical. The unit features a delivery pressure range of 0-60 PSIG and is rated for a maximum inlet pressure of 1200 PSIG. The core of its precision lies in the stainless steel diaphragm, which provides superior sensitivity compared to elastomeric alternatives and eliminates the risk of outgassing, ensuring the integrity of the gas stream is maintained.

Construction-wise, the regulator is machined from rugged brass bar stock, providing a dense, non-porous body that is essential for high-purity gas handling. The body, bonnet, and gauges are fully plated, offering enhanced corrosion resistance and a clean aesthetic suitable for laboratory settings. A key technical feature is the filtered seat mechanism. This design element not only contributes to the purity of the gas stream by trapping potential particulates but also significantly extends the service life of the regulator by preventing seat damage. The unit is equipped with a large, easy-to-read 2-1/2 inch single scale gauge, allowing operators to monitor delivery pressure with accuracy.

The 201-80-11 is configured with a 1/4" MPT inlet and a 1/8" brass tube fitting outlet, facilitating integration into standard analytical piping systems. The body is also tapped for rear panel mounting, providing flexibility for installation in instrument consoles or gas management panels. It is specifically recommended for use with inert and non-corrosive gases and is engineered to withstand vacuums generated during purging operations, a common procedure in analytical workflows to eliminate atmospheric contamination.
